PENCIL SHARIPENER.

v Application inea January 25, 192,2, serial -of which the specification has been filed on January25, 1922, under Serial No. 531,623.

This invention relates to pencil sharpeners, having more particular reference to the type comprising a fixed blade set in av suitable socket.

The invention has for an object to provide a novel pencil sharpener adapted for suspension from a watchchain, key holder, neck ribbon or the like, other objects relating to the combining of an eraser with the sharpener and the detachment of the Sharpener from its suspension means.

For further comprehension of the invention, and of the objects andv advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth. p

Fig. l of the drawings is a side'view of one form of my improved pencil Sharpener.

Fig. 2 is a side view showing a slightly modified form of eraser.

Fig. 3 is a side view of the eraser removed.

Fig. 4 is a side view showing a further modification.

Fig. 5 is a detail side view 0f the eraser provided in Fig. 4.

Fig. 6 is a part side view and part axial sectional view of another form of the pencil Sharpener.

Fig. 7 is a fragmentary axial sectional view at right angles to Fig. 6.

In constructing my improved pencil Sharpener I provide a tubular member 10 having integral at one end a tapered socket element 11. The socket element 11 is longitudinally slotted on one side as at 12 to rceeive the knife blade The latter is can ried on a tongue 14 formed on the edge of slot 12 and adjustably held in place by screws 15 passing through transverse slots 16 in the knife and threaded into the tongue.

The opposite end of the tubular member 10 has frictionally inserted therein a short cylindrical member 18 in the inner end of which is fixed an eraser 19 of the usual rubber material. The outer end of member 10 is no. 531,623. Renewed November 14, 1923.

in the form of an enlarged head 2O which may be rounded or polygonal form as may be desired. A short distance from thishead 20 a peripheral bead 21 is formed on member 13 to limit its insertion into the member 10 by engaging the end thereof. This construction, as so far described, is commonto the Sharpeners shown in Figs. 1 and 2 of the drawings. v e

To suspend the Sharpener from the watchchain, key ring, or neck ribbon I have shown in Fig.V 1 a pair of apertured lugs 23 xed tothe memberv 10l and engaged by eye elements 24 formed on the ends of a bail 25. Intermediate its ends this bail is bent .to form a loop 26 in which is a ring 27 .to which the chain or neck piece may be attached. In Fig. 2 I show a bail 25 having a similar loop 26 holding a ring 27 but having its ends inturned to pivotally engage in srarss narrar orrics. f

sockets 22 formed on the side of the memv ber 10.

In the form of pencil Sharpener shown in Figs. 4 and 5 I provide integral tubular and socket elements 10 and 11 and a knife 13, these parts corresponding in construction to Athe parts 10, 11, 13 except that the open end of the tubular member is interiorly screw threaded as at 30.

In this modification the eraser 19 is fixed in a cylindrical member 18 having exterior screw threads 33 whereby it may be screwed into the member 10. This member has an enlarged head 20 on which is fixed an eye 31 carrying a ring 32 to receive the suspending element.

In the form of the invention shown in Figs. 6 and 7 I provide a cylindrical member 10a, socket 11L and knife 13a similar to those already described except for the means for suspension from a bail 25a. In this arrangementthe'member 10 is pressed outwardly onopposite sides near its open end as at 35 to form a pair of circular' recesses. In these recesses engageV disk-heads 36 formed on the inturned ends 37 of the bail 25"', slots 33 being extended inwardly from the open end of the member 10a to permit of insertion of the bail ends 37. An eraser 19a and its holder 18a such as shown in Fig. 3 is inserted friotionally into the open end of member 10a.

As will be apparent the bail 25a cannot be freed from member 1()a while the eraser holder 18a is in place, while the legs of the outward pressure on the parts 35 so that if it is desired to remove the sharpener from the bail the eraser is first removed and the legs of the bail pressed inwardly, freeing the heads 36 from the recesses in which they engage and allowing the ends 37 to pass outwardly through the slots 38.

Having thus described my invention what claim as new and desire to protect by Letters atent of the United States is as tollows:

l. in device of the ciass described, a tubular member7 a plug irictionally engaged in one end of said tubular member, and a suspension bail connected to said tubular member and held against disengagement therefrom by said plug.

2. 'n a device of the class described, a tubular member, a plug irictionally engaged in one end 01"' said tubular member, a suspension bail connected to said tubular member, said bail having inturned ends pro- :terasse vided with disk-heads, said tubular inember presenting recesses in the inner face of `the Wall thereof receiving said heads and having slots entering from the end thereof to the said recesses for the passage of the said inturned bail ends.

3. In a device of the class described, a tubular member, a plug frictionally engaged in one end of said tubular member, a suspension bail connected to said tubular member, said bail having inturned ends provided with disk-heads, said tubular member presenting recesses in the inner face of the Wall thereof receiving said heads and having slots entering from the end thereof to the said recesses for the passage of the said inturned bail ends, the said plug engaging the said disk-heads to prevent Withdrawal of the same from the said recesses.

In testimony whereof l have affixed my signature.
